Monitoring Systemic Dynamic Effects following Disturbances affecting HVDC Power Transmission in the BIPS using WAMS Infrastructure
This paper introduces a conceptual framework and infrastructure designed to monitor the dynamic behavior of the Brazilian Interconnected Power System (BIPS) following disturbances that affect power transmission in High Voltage Direct Current (HVDC) links. Monitoring is devised in light of a set of proposed System Severity Indicators (SSIs), whose computation depends upon synchrophasor data collected at converter stations and conveyed to a phasor data concentrator (PDC) placed in the control center of the Brazilian System Operator (BSO). Numerical results are acquired using electromagnetic transient (EMT) simulation and actual disturbance records, including cases with commutation failures and DC transmission line fault events. The results highlight the applicability of the proposed indicators on featuring the severity of events to the transient stability of the BIPS.
